摘要：

Precise conductance measurements were carried out on Bu3N(CH2)8NBu3Br2, Pr3N(CH2)6NPr3Br2, Et3N(CH2)4NEt3Br2, MeN(CH2CH2)3NMeBr2, and MeN(CH2CH2)3NMeI2 in water at 10 and 25° and on Bu3N(CH2)8NBu3Br2 in methanol in 10 and 25°. From a comparison of the limiting ionic mobilities and concentration dependence of the tetraalkylammonium ions and these large bolaform ions, it is concluded that cation-cation pairing does not make a significant contribution to the concentration dependence of R4N+ ions in dilute aqueous solutions. In addition, when the concentration dependence for these salts in aqueous solution is compared to that observed in other hydrogen bonding solvents, many similarities are observed. It is likely that part of their peculiar behavior which has been attributed to the structural features of aqueous solution is a general property of hydrogen bonding solvents.
